EPA 608 exam type 1 practice questions and answers
2025\2026 A+ Grade
before beginning a refrigerant recovery procedure it is always necessary to ___
- correct answer know the type of refrigerant that is in the system.
at high temperatures, (i.e. open flames, glowing metal surfaces, etc.) R-12 and R-22 can decompose to
form ____
- correct answer phosgene gas
the system dependent (passive) recovery process _______
- correct answer Recovers refrigerant in a non-pressurized container
which of the following refrigerants must be recovered with equipment currently regulated by the
equipment certification requirements of the EPA under section 608?
- correct answer Methyl Chloride
Refrigerants (ie. R-12, R-22, R-500, etc.) in large quantities can cause suffocation because _____
- correct answer they are heavier than air and displace oxygen
what is the maximum allowable factory change of refrigerant for Type I appliances?
- correct answer 5 pounds
A storage cylinder of recovered R-22 at normal room temperature (about 75°F), in the absence of non-
condensable, will be pressurized to _____
- correct answer 130 psig
, The sale of CFC and HCFC refrigerants is ______
- correct answer restricted to technicians who are EPA certified in refrigerant recovery
if a large leak of refrigerant occurs such as from a filled cylinder in an enclosed area, what action should
be taken when no SCBA is available?
- correct answer vacate and ventilate the spill area
when using recovery cylinders and equipment with schraeder valves, it is "critical" to _____
- correct answer inspect the schraeder valve core for bends and breakage, replace any damaged
shraeder valve core to prevent leakage, cap the shraeder ports to prevent accidental depression of the
valve core.
D all of the above
at high temperatures (ie., open flames, glowing metal surfaces etc.) R-12 and R-22 can decompose to
form ______
- correct answer Hydrochloric and Hydrofluoric acids
when a household refrigerator compressor does not run, it is recommended that low and high side
access valve be installed when recovering refrigerant from the system because _____
- correct answer it can enhance the speed of recovery
It may be necessary to achieve required recovery efficiency
using the system dependent (passive) recovery process, which condition requires accessing both the
high and low side of the system for refrigerant recovery?
- correct answer when the compressor does not run
When R-500 is recovered from an appliance, it _____
- correct answer must be recovered into its own recovery vessel that is clearly marked to ensure that
mixing of refrigerants does not occur
when filling a graduated charging cylinder, refrigerant that is vented off the top of the cylinder
_________
- correct answer must be covered
